Screw Spike

A screw spike, also named sleeper screw or railway threaded spike, is a specialised heavy‑load threaded fastener made to fix rail clips, base plates and steel rails firmly onto concrete, timber or composite railroad sleepers.

Unlike ordinary smooth railroad spikes hammered into sleepers, the screw‑spike uses coarse self‑tapping threads to create a solid mechanical anchor. It can resist repeated vibration, dynamic compression, impact load and temperature shift brought by high‑speed and heavy‑haul trains. For every new‑build railway, urban metro and routine track‑maintenance project, reliable screw‑spike hardware directly determines track stability and travelling safety.

Different working‑conditions require dedicated surface‑treatment solutions for your screw‑spike:

1. 1.Black oxide finish: Low‑cost option for inland dry‑climate temporary rails and mine haulage tracks.
2. 2.Hot‑dip galvanizing: The most popular choice for main‑line railways, delivering thick zinc coating against rust and moisture erosion.
3. 3.Dacromet coating: Suitable for coastal, high‑salt‑spray environments, with superior salt‑spray resistance compared to ordinary galvanised finish.
